Error "Server connection interrupted. Refresh" shows while using nginx reversing proxy to openshift web console

[eliu]

I use nginx to create a reverse proxy to the OpenShift web console for some reason. The web page can display but shows Server connection interrupted error notification intermittently.

The nginx conf file is something like this:

server {
   listen 80;
   server_name *.app.example.com;
   location / {
       proxy_set_header Host $host;
       proxy_set_header X-Real-IP $remote_addr;
       proxy_pass http://192.168.123.155/;
   }
}
server {
    listen 8443 ssl;
    server_name master.example.com;
    ssl_certificate     master.server.crt;
    ssl_certificate_key master.server.key;
    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers         HIGH:!aNULL:!MD5;
    location / {
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_pass https://192.168.123.155/;
    }
}

probably need some wisdom from @knobunc team ;-)

That message means there are issues establishing websocket connections. Check that you have properly configured nginx to allow websocket connections through.

@jwforres thanks for the tips! Now the error notification faded away after handling websocket stuff within nginx.

@jwforres would you mind sharing the nginx configuration that you ended up with that worked?
